Base Bankr (Doppler) API
This page provides a set of queries to track tokens launched by Bankr on Base. Bankr deploys tokens using the Doppler Protocol (canonical contracts maintained by Whetstone Research). Each token is minted into the Doppler Airlock orchestrator, seeded into a Uniswap V4 multicurve pool via an initializer contract, and traded on V4 from the moment it launches.
Bankr uses Doppler's NoOpMigrator, which means liquidity never migrates — the multicurve LP stays in the same V4 pool forever and fees stream out through StreamableFeesLockerV2 to the creator and Doppler. Because of this, there is no on-chain Graduated event for Bankr tokens; "graduation" is inferred from curve exhaustion (initializer's token balance reaching zero, or the pool tick crossing the final curve segment).

To query or stream data via GraphQL outside the Bitquery IDE, you need to generate an API access token. Follow the steps here: How to generate Bitquery API token ➤.
Bankr / Doppler Contract Map (Base)
| Component | Address | Role |
|---|---|---|
| Airlock | 0x660eAaEdEBc968f8f3694354FA8EC0b4c5Ba8D12 | Orchestrator — emits Create per launch, receives the initial mint |
| DecayMulticurveInitializer | 0xd59ce43… | Holds the V4 LP position (current default) |
| ScheduledMulticurveInitializer | 0xA36715d… | Holds the V4 LP position (original Feb 2025 deployment) |
| Uniswap V4 PoolManager | 0x498581fF718922c3f8e6A244956aF099B2652b2b | Singleton where swaps actually clear |
| NoOpMigrator | (reverts on call) | Bankr's migrator slot — disables migration by design |
Latest Tokens Launched via Bankr
Every Bankr launch emits a Create(address,address,address,address) event on the Airlock contract. This query returns the most recent launches with the new token address and deployer.
{
EVM(network: base) {
Events(
limit: { count: 25 }
orderBy: { descending: Block_Time }
where: {
LogHeader: {
Address: { is: "0x660eAaEdEBc968f8f3694354FA8EC0b4c5Ba8D12" }
}
Log: { Signature: { Name: { is: "Create" } } }
}

Transaction {
Hash
From
}
Arguments {
Name
Value {
__typename
... on EVM_ABI_Address_Value_Arg {
address
}
}
}
}
}
}
The four positional arguments are typically (asset, numeraire, initializer, migrator). The first address is the newly created token; the third is the multicurve initializer holding its LP; the fourth identifies whether the launch uses NoOpMigrator or a real migrator.
Recent Bankr Tokens Created by a Deployer
Filter Create events on the Airlock by Transaction.From to list every Bankr token launched by a specific wallet. Replace the deployer address with the wallet you want to track.
{
EVM(network: base, dataset: realtime) {
Events(
limit: { count: 50 }
orderBy: { descending: Block_Time }
where: {
Log: {
SmartContract: { is: "0x660eaaedebc968f8f3694354fa8ec0b4c5ba8d12" }
Signature: { Name: { is: "Create" } }
}
Transaction: {

Transaction {

From
}
Arguments {
Name
Value {
__typename
... on EVM_ABI_Address_Value_Arg {
address
}
}
}
}
}
}
The first address in Arguments is the newly minted token contract.
